USE OF NEXT/PREV SCREENS/LEVELS
Weld schedules contain more data than can be shown at one time. To display this
data the NEXT/PREV SCREEN keys and NEXT/PREV LEVEL keys must be
used. These keys are located at the corners of the lower display. When there is
more data on another screen or level, a flashing * will appear in the appropriate
corner (s) to indicate that more information is available.
Screen/Level keys are used in selection of a weld schedule and all weld schedules
use 4 basic screens that appear in the following order:
1. PROMPT SCREEN - Appears when a weld schedule is called up from
memory.
2. LEVEL 01 AMPS - TIME - PULSE = Displays the value of AMPS, LEVEL
TIME and PULSE TIMES for LEVEL 1.
3. LEVEL 01 RPM - MODES = Displays the value of ROTATION RPM,
PULSE MODE and TRAVEL MODE for LEVEL 1.
4. PURGE - SLOPE - ROT DELAY = Displays the time for PREPURGE,
POSTPURGE, UPSLOPE, DOWNSLOPE and ROTATION START
DELAY.
Pressing the NEXT SCREEN key will advance the display in the above order.
When viewing screen 2, 3 or 4 (above) pressing the PREV SCREEN key will
reverse the order.
